Description

Technical Field

[0001] This utility model belongs to the field of geotechnical engineering protection technology, and specifically relates to a prefabricated modular reinforced concrete block for slope protection. Background Technology

[0002] Traditional slope protection methods often employ anchor bolt support, shotcrete mesh support, cast-in-place concrete, or loose masonry. These methods suffer from problems such as long construction cycles, unstable quality, difficulty in disassembly and reuse, and poor ecological performance. Meanwhile, current precast concrete blocks mostly rely on unidirectional interlocking, resulting in insufficient three-dimensional spatial stability, making them unable to adapt to the loads of complex slopes. Furthermore, the large mass of concrete blocks makes construction inconvenient. All these factors are detrimental to slope protection work. Utility Model Content

[0003] To address the existing technical problems, this utility model proposes a prefabricated modular reinforced concrete block for slope protection, which solves the current problem of inconvenient slope protection construction.

[0004] The purpose of this utility model and the technical problem it solves are achieved by the following technical solution. According to this utility model, a prefabricated modular reinforced concrete block for slope protection includes a hollow block body. On two corresponding surfaces of the block body, there are matching first, second, and third locking parts. Inside the block body, there are interconnected first reinforcing ribs extending along the length direction, second reinforcing ribs extending along the width direction, and third reinforcing ribs extending along the height direction. On any surface of the block body, there are several through holes that penetrate the outer wall of the block body and communicate with the interior of the block body.

[0005] Furthermore, the first snap-fit ​​part includes a guide groove on the front side of the soil block body, and a guide block that matches the guide groove is provided on the rear side of the soil block body, with the guide block slidingly embedded in the guide groove.

[0006] Furthermore, the second snap-fit ​​part includes a male connector on the left side of the soil block body, and a female connector hole matching the male connector on the right side of the soil block body. The male connector is provided with a guide bar, and the inner wall of the female connector hole is provided with a sliding groove that cooperates with the guide bar.

[0007] Furthermore, the second snap-fit ​​part includes a male connector on the left side of the soil block body, and a female connector hole matching the male connector on the right side of the soil block body. The male connector is provided with a guide bar, and the inner wall of the female connector hole is provided with a sliding groove that cooperates with the guide bar.

[0008] Furthermore, a connector is screwed onto the outer wall of the protrusion, and an anchor is fixed to the bottom of the connector.

[0009] Furthermore, the upper surface of the soil block is symmetrically provided with lifting holes that can be detachably connected to the lifting ring.

[0010] Furthermore, each surface of the soil block is textured with a roughened layer.

[0011] In summary, this utility model, through its three-dimensional interlocking design, allows for the rapid assembly of multiple concrete blocks to form a grid structure, exhibiting strong stability and anti-overturning capabilities, and facilitating disassembly and reuse. Simultaneously, the hollow design of the soil blocks, with numerous holes and reinforcing ribs on the outer wall, reduces the weight of the soil blocks while ensuring their strength. Furthermore, the holes allow for planting grass to provide ecological restoration, facilitating use and aiding in slope protection work. The detachable anchors further solidify the connection between the bottom soil blocks and the slope, and the roughened layer enhances the friction between adjacent soil blocks, preventing slippage and ensuring the stability of the slope protection.

[0012] The above description is merely an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this utility model more obvious and understandable, preferred embodiments are given below, and detailed descriptions are provided in conjunction with the accompanying drawings.

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and preferred embodiments. For clarity, the descriptions of front, back, left, right, up, and down directions in this utility model are all based on... Figure 3 direction shown.

[0020] Please see Figure 1 , Figure 2 A prefabricated modular reinforced concrete block for slope protection includes a hollow block body 1, with a first snap-fit ​​part 2, a second snap-fit ​​part 5, and a third snap-fit ​​part 4 respectively provided on two corresponding surfaces of the block body 1.

[0021] The first engaging part 2 includes a guide groove on the front side of the soil block body 1, and a guide block matching the guide groove on the rear side of the soil block body 1. The guide block is slidably embedded in the guide groove. In this embodiment, the guide groove is a T-shaped groove, and the guide block is a T-shaped guide block. The guide block can be slidably embedded in the guide groove to achieve interlocking with the adjacent longitudinal soil block body 1. The second engaging part 5 includes a male connector on the left side of the soil block body 1, and a female connector matching the male connector on the right side of the soil block body 1. In this embodiment, the male connector and the female connector are matching frustum shapes. The male connector can be inserted into the female connector, and the inclination angle of the contact surface between the two is 15°-20°. At the same time, the male connector is provided with a guide strip 6, and the inner wall of the female connector is provided with a guide strip 6 that cooperates with the guide strip 6. The guide bar 6 and the sliding groove cooperate to achieve self-locking and pull-out resistance between the horizontal soil blocks 1; the third locking part 4 includes a tenon on the upper surface of the soil block body 1, and a countersunk hole matching the tenon on the lower surface of the soil block body 1. In this embodiment, the tenon and the countersunk hole are corresponding frustoconical shapes. At the same time, the top of the tenon is provided with a concave hole 7, and the countersunk hole is provided with a protrusion 10 that cooperates with the concave hole 7. When the tenon is inserted into the countersunk hole, the concave hole 7 and the protrusion 10 are connected to each other to achieve double locking, thereby realizing the insertion and positioning between the vertical soil block bodies 1; through the three-dimensional interlocking design of horizontal, vertical and longitudinal dimensions, multiple concrete blocks can be quickly spliced ​​to form a grid structure, which has strong stability and anti-overturning ability, and facilitates the disassembly and reuse of the soil block body 1; please also refer to Figure 5 A connector 12 is screwed onto the outer wall of the protrusion 10, and an anchor 13 is fixed to the bottom of the connector 12. During construction, there is no need to align the tenon in the countersunk hole of the lowest soil block body 1. The connector 12 (e.g., an internal threaded sleeve, one end of which is screwed to the protrusion 10 and the other end is welded to the anchor) can be used to connect the anchor and insert it into the slope to improve the pull-out resistance of the soil block body 1. Furthermore, a roughened layer is processed on any surface of the soil block body 1, which can improve the anti-slip performance between the soil block bodies 1 after assembly, avoid misalignment, and further improve the slope stability.

[0022] The upper surface of the soil block body 1 is symmetrically provided with lifting holes 14 that can be detachably connected to the lifting ring. Existing lifting rings can be screwed into the lifting holes 14 to facilitate the lifting construction of the soil block body 1.

[0023] Please see Figure 1 , Figure 3Several through holes 3 are provided on any one surface of the soil block body 1. The through holes 3 penetrate the outer wall of the soil block body 1 and are connected to the interior of the soil block body 1. The number of through holes 3 is determined according to production needs. Soil and grass can be filled in the through holes 3 to provide ecological restoration function. Furthermore, the hole structure can reduce the amount of concrete used in the soil block, thereby reducing the weight and facilitating construction.

[0024] Please see Figure 4 The soil block body 1 is provided with a first reinforcing rib 11 extending along the length direction, a second reinforcing rib 8 extending along the width direction, and a third reinforcing rib 9 extending along the height direction, which are connected to each other. The first reinforcing rib 11 and the second reinforcing rib 8 located on the same horizontal plane are vertically connected, and the third reinforcing rib 9 is vertically connected at the intersection of the two aforementioned reinforcing ribs, thus ensuring the strength of the soil block body 1.

[0025] The above description is merely a preferred embodiment of this utility model. Any simple modifications, equivalent changes, and alterations made by those skilled in the art to the above embodiments based on the technical essence of this utility model without departing from the scope of the technical solution of this utility model shall still fall within the scope of the technical solution of this utility model.
